Canadian Prime Minister Justin Trudeau says his government had no involvement in the arrest of a top executive from Chinese technology giant Huawei, who was detained at Vancouver airport. Trudeau said Ottawa had been given a few days' advance notice about the plan to arrest Meng Wanzhou, who faces extradition to the United States. He declined to give further details, given that Meng faces a bail hearing on Friday. The news pummelled stock markets already nervous about increased tension between the United States and China and prompted experts to predict that Beijing would retaliate against Canada. "The appropriate authorities took the decisions in this case without any political involvement or interference ... we were advised by them with a few days' notice that this was in the works," Trudeau told reporters in Montreal in televised remarks. Asked whether he had spoken to the Chinese premier or the ambassador, Trudeau said he had had no conversations with international counterparts about the case. China's embassy said late on Wednesday that it firmly opposed what it called an unjustified arrest. The move comes at a challenging time for Trudeau, whose attempts to boost trade ties with China are sputtering. Brock University professor Charles Burton, a former Canadian diplomat who had served two postings in China, said Beijing was convinced the US administration had pressured Canada to go ahead with the arrest. "We can expect China to retaliate against Canada very vigorously," he said by email. In June 2014, Chinese businessman Su Bin was picked up on a US warrant in Canada, where he had been attempting to establish residency. Shortly afterwards a Canadian citizen in China was arrested and charged with spying. Kevin Garratt spent two years in detention before being deported.

Canadian PM denies role in Huawei arrest

Canadian Prime Minister Justin Trudeau says his government had no involvement in the arrest of a top executive from Chinese technology giant Huawei, who was detained at Vancouver airport.

Trudeau said Ottawa had been given a few days' advance notice about the plan to arrest Meng Wanzhou, who faces extradition to the United States. He declined to give further details, given that Meng faces a bail hearing on Friday.
